NOZZLE FOR COTTON-PICKIN Gr MACHINES.

Specification of Letters Patent.

Patented May 2, 1916.

To all whom it may concern:

Be it known that I, Jnssin F. BEARD, a citizen of the United States, residing at Binger, in the county of Caddo and State of Oklahoma, declare that I am executrix of the will of WILLIAM CooK, deceased, who invented a new and useful Nozzle for Cotton-Picking Machines, of which the following is a specification.

This invention relates to nozzles for use in connection with cotton picking machines of that type utilizing suction for the purpose of removing the cotton fiber from the burs and conveying it into the machine.

One of the objects of the present invention is to provide a picking nozzle adapted to receive the cotton fiber and which is provided with means whereby the nozzle is rotated by the suction set up within the machine, thereby operating more efficiently to remove the cotton from the plants.

A further object is to provide nozzle rotating means which obviates the necessity of utilizing complicated mechanism such as have heretofore been employed for rotating the nozzles.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the com bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawingsz Figure l is a side elevation of a picking nozzle such as constitutes the present invention, a portion of the flexible tube to which it is attached being shown. Fig. 2 is a central longitudinal section through the nozzle. Fig. 3 is a section on line AB, Fig. 2. Fig. 4 is a rear elevation of the nozzle.' Fig. 5 is a front elevation of the inlet end of the nozzle.

Referring to the figures by characters of reference 1 designates a cylindrical sleeve having a concentric ring 2 in one end thereof, said ring being connected to the sleeve by radial arms 3 or in any other suitable manner. Another ring 4 is connected to the sleeve 1 by means of arms 5 which extend forwardly from the sleeve and converge toward the ring 4;. Each of the rings 2 and 4 constitutes a race for antifriction balls 5 which engage collars 6. These collars are interposed between the rings 2 and 4t and extend around a tube 7 extending through and concentric with the rings 2 and 4:. An annular series of fan blades 8 is secured to the tube 7 and within the cylindrical sleeve 1, these blades extending close to but being out of contact with the sleeve. The fan blades are so pitched that when a current of air is passing through the sleeve 1, the tube 7 will be caused to rotate within the rings 2 and 4:.

The outer end of the tube 7 is flared, as shown at 9 to form an inlet and extending inwardly from this flared portion are pronged pins which can be disposed at different distances from the extremity of the tube, as shown.

It is to be understood of course that the sleeve 1 is to be secured within one end of a flexible tube 11 connected to a suction element. When suction is set up through the tube 11 the air will enter tube 7 and also will flow between the blades 8 of the fan. When the inlet or flared end 9 of the tube 7 is unobstructed, air will enter the tube 11 freely and said tube will have little if any rotation due to the pressure of air against the fan blades 8. When, however, the flared end 9 is placed against a cotton boll, thus partly or entirely closing the outer end of tube 7, the suction set up through the nozzle will cause the air to press forcibly against the blades 8 with the result that said blades will rotate the tube 7. The cotton fiber is drawn into the tube and engaged by the teeth 10 and is thus sucked and twisted from the bur and, when released, is drawn through the tube 7 into tube 11.

What is claimed is A suction nozzle for cotton picking machines, including a sleeve, a bearing ring concentric therewith and within one end portion thereof, radial arms connecting said ring to the sleeve, another bearing ring, arms diverging from said ring and connected to the sleeve, said arms constituting means for holding the ring spaced beyond the sleeve, there being air inlet openings be tween said diverging arms forming straight unobstructed air passages through the sleeve, a tube mounted for rotation in the path of an air current flowing through the sleeve, and teeth arranged Within the flared end of the tube and disposed at different distances from the extremity thereof.

In testimony that I claim the foregoing as 15 my own, I have hereto aflixed my signature in the presence oftwo Witnesses.
